Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary equipment technology, specifically a drawer guide rail for a medical trolley. Background Technology

[0002] Medical trolleys typically have drawers under the top panel. Existing medical trolleys use metal drawer slides, which are not only expensive but also prone to jamming when the ball bearings are not properly lubricated. They are also bulky. The back of the trolley top panel also requires a specific mounting structure. The applicant has designed a medical trolley top panel and drawers with handles on all four sides. Their combination allows drawers to be added to either side of the top panel of the medical trolley. The slide structure is one of the key components, and the applicant will implement separate and effective protection for it. Utility Model Content

The connecting holes are set on the outer side plate, and the spacing between the connecting holes is the same as the spacing between the connecting posts of the guide rail.

[0005] Furthermore, the guide rail has a U-shaped structure, including an outer side plate, connecting holes, an inner side plate, a bottom plate, a straight groove, and a connecting edge. The straight groove is formed by the outer side plate, the inner side plate, and the bottom plate, and is located between the outer side plate and the inner side plate. The connecting edge is located on the outer side of the outer side plate, and the top surface of the connecting edge is on the same plane as the top surface of the bottom plate. The connecting holes are located on the connecting edge, and the spacing between the connecting holes is the same as the spacing between the connecting posts of the guide rail.

[0006] Furthermore, the height of the downward protrusion of the guide rail corresponds to the height of the inner side plate of the guide rail.

[0007] The drawer that is compatible with this utility model is a concave box body formed by two longitudinal side walls, two transverse side walls and a bottom wall. The longitudinal side walls and transverse side walls are provided with handle grooves. The upper end of the longitudinal side walls and transverse side walls is provided with an extended top surface. A guide rail is provided on the outer side of the extended top surface. An avoidance notch is provided at the junction of two adjacent guide rails. The guide rails protrude downwards, and the height of the downward protrusion of the guide rails corresponds to the height of the inner side plate of the guide rail.

[0008] The top plate structure used in conjunction with this utility model is as follows:

[0009] The lower surface of the board is fixed with longitudinal and transverse ribs and guide rail connecting posts. The longitudinal and transverse ribs are vertically distributed and fixedly connected to each other. The lower surface of the board has two or more rows of parallel and spaced guide rail connecting posts and drawer top edge strips. The longitudinal and transverse ribs are set between two adjacent rows of guide rail connecting posts and drawer top edge strips. The guide rails of this utility model are fixedly installed on the guide rail connecting posts, and the drawer is on two parallel guide rails. The mounting slot is provided with an upper polished hole, an inner stepped hole, and a lower polished hole along the axial direction. The double-ended connector is circumferentially limited and fitted into the inner stepped hole. The platform connector is fitted into the upper polished hole, and the support column is fitted into the lower polished hole. The platform connector and the support column are respectively fixedly connected to the two ends of the double-ended connector to realize the fixed connection between the plate and the support column. The height of the drawer top edge strip is the same as the height of the guide rail connecting column. The height of the longitudinal rib and the transverse rib is less than the height of the drawer top edge strip. The drawer top edge strip is connected to the guide rail connecting column in the same row. In each row of guide rail connecting columns and drawer top edge strips, the guide rail connecting column is set on one side of the drawer top edge strip. A limiting post is provided at the rear limit end of each row of drawer top edge strips to prevent the drawer from shifting in the opposite direction.

[0010] If four rows of parallel, spaced-apart guide rail connecting columns and drawer top edge strips are provided on the lower surface of the plate, then two drawers can be installed under the top plate.

[0011] The drawer is a concave box formed by two longitudinal side walls, two transverse side walls and a bottom wall. Both longitudinal and transverse side walls are provided with handle grooves. Both longitudinal and transverse side walls are provided with extended top surfaces. Guide rails are provided on the outer side of the extended top surfaces. There are clearance notches at the intersection of two adjacent guide rails. The guide rails protrude downwards.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model features multiple rows of guide rail connecting columns 6 on the lower surface of the top plate, facilitating the installation of drawer rails. One or two drawers can be conveniently installed under the top plate. Drawers and guide rails with specific structures can be combined with a top plate of a specific structure, allowing the trolley to be freely equipped with one or more drawers, and the drawer's pull-out direction can be determined. This design increases the trolley's storage space, allowing medical staff to categorize and store different types of medical supplies in the drawers for easy access and management, thus improving work organization.
